Hi, I'd like to recommend It All Began With A Lawsuit. It's by snowflake16. It features Kris Wu and Jung Eun Mi (OC). It's a romance fic based on his lawsuit. Genres: romance, angst, drama.

Author-nims writing gives Kris fans the healing power they're looking for. I can't believe its going to end soon.
"A member of Korea's biggest boy bands decides to sue his company in the midst of their comeback period. Fighting alongside him is his lawyer and an intern. The media explodes as he mysteriously vanishes. The fans implode. Will he escape the clutches of the company or will he stagger back to them? To an onlooker it ma y seem that the choice is his but is it really? And amongst all this can a thing such as friendship and true love really be found? This story begins on the day the media reports about Kris leaving SM and will progress for a duration of a five span."

"Broken Vow" is a good fanfic. the author is millionfandoms :))
